Not disagreeing with you, but my first thought about that "Newmarket" comment was only just as a reference to the direction the sighting headed, no more. Make sense? A guy crossed the road towards the Esso garage, that's it - maybe to hitch from customers? Better than hitching on the main road at 4.30 am perhaps?
All we know is that C never made it back to Honington.
Does anyone else think the sighting near a very large Base is relevant, possibly being dropped off within yards of it ? ETA I mean Lakenheath of course.
By saying the road-crosser seemed to be headed toward Newmarket, that seems to mean that he was on the BM to BSE side of the road and crossing over to the BSE to BM side of the road? This would be the wrong way around for Corrie if he'd hitched a lift and got out prior to the Fiveways roundabout. Having said that I haven't checked the location of the Esso on a map to see which side that is on.
I find the sighting to be suspicious. It's too perfect. 70 mph, refer to the twilight times in Melmoth's post and approx 4-4.30 am, and the driver can not only see a pink shirt (which he may be fitting in after-the-fact) but also the brown boots. So he's definitely filling in memories after-the-fact in that he wouldn't have been able to make out these specific colours at the time and speed. If it's near the roundabout then the driver must be slowing from 70mph (I'm a non-driver but you can't approach a roundabout at that speed). At any speed seeing someone running across the road will stand out at that time of night/early morning, and I presume at close to 70mph there'd be a part of the brain wondering if you need to hit the brakes to avoid this person, because they've stopped on the central reservation and you don't know exactly when they're going to cross? Or was driver going from BM to BSE and on that side of the road...which makes less sense to my brain as there doesn't feel like enough time to see the person cross and also stop at the barrier and then cross the other side....did the driver say he saw the person cross both sides or only one?
I can see someone sticking their foot on the barrier in the central reservation, but I can't see Corrie adjusting his jeans at the boots end at that point. It gives me an image of someone posing for the driver to explain how he could see so much detail in the dark. Sure, maybe someone did put their foot on the barrier to hop over the barrier. But I find it hard to believe colours were visible more than 'pale-ish shirt and trousers and dark boots', so I'm with Ironside on this one and calling it doubtful. Of course it should still be considered, but without any corroborative evidence it doesn't sound very strong to me.
The Brandon keys weren't Corrie's keys. It was months later, the keys looked like they were dropped in the past few hours, not months. It was a residential street with hundreds of garages and parking spaces, ergo the keys were from a car that was recently parked down that road. JMO.
The Esso garage would be a good place to get a drink, snack, or hitch a lift. But Corrie would also have to avoid being caught on CCTV and avoid every single person around the garage, with the possible exception of one who does give him a lift but doesn't come forward.
I don't think we have enough detail on the phone pings to map them out. We've now got newspapers telling us the pings went to Milton....but initially we were told that the pings stopped within a mile or so of the BM roundabout, and the times we have are all over the place and don't converge over time to anything solid, they just continue to be all over the place. If anything they are converging on the bin lorry times and not away from the bin lorry.
